| |
With the following configuration options: CONFIG_OF is not set CONFIG_MTK_PMIC_WRAP=y CONFIG_MTK_SCPSYS=y we get the following build warnings:
CC drivers/soc/mediatek/mtk-pmic-wrap.o drivers/soc/mediatek/mtk-pmic-wrap.c:2138:34: warning: ‘of_pwrap_match_tbl’ defined but not used [-Wunused-const-variable=] drivers/soc/mediatek/mtk-pmic-wrap.c:1953:34: warning: ‘of_slave_match_tbl’ defined but not used [-Wunused-const-variable=] CC drivers/soc/mediatek/mtk-scpsys.o drivers/soc/mediatek/mtk-scpsys.c:1084:34: warning: ‘of_scpsys_match_tbl’ defined but not used [-Wunused-const-variable=]
Looking at the code, both drivers can only bind to OF-defined device nodes, so these drivers are useless without OF and should therefore depend on it.
Developers or QA teams who wish to test-build the code can still do so by enabling CONFIG_OF, which is available on all architectures and has no dependencies.
